Hello guys, I have a 88 924s that had a snapped timing belt while driving. As an interference engine, I worry of bent valves And a ton of money going to be spent (BTW my dad did it not my fault). Since I have not yet looked under the valve cover to actually inspect the damage, I'm looking for advice and help.
What could be broken and needs replacing without looking first?
What would you do.
And to inspect, can I leave the engine in or do I have to take it out.
Tia any constructive help appreciated.

Thank you for the response! It's his car that we barely used because 80% of it being in our position has not run. I just got into cars so I know understand the importance of car maintenance. The belt broke around December of 2014 and I plan on trying to fix her up.
